What is the total resistance in the above diagram?
5 ohms
15 ohms
25 ohms
35 ohms
45 ohms
Correct answer is C
Resistance in series will be given as R = 10+10 → 20
Resistance in parallel will be given as \(\frac{1}{R}\) = \(\frac{1}{10}\) + \(\frac{1}{10}\)
\(\frac{1}{R}\) = \(\frac{2}{10}\) → \(\frac{1}{R}\) = \(\frac{1}{5}\)
Resistance in parallel = 5
Total resistance = 20 + 5 → 25ohms
